1. Composition: Mixtures have a variable composition, meaning the proportions of the components can vary. Each mixture can have a different composition, depending on how it was formed. Compounds, on the other hand, have a fixed and definite composition. The proportions of the elements or molecules in a compound are always the same.
2. Properties: Mixtures exhibit the properties of their individual components. For example, a mixture of sand and salt will have the properties of both sand and salt. Compounds, however, have unique properties that are different from the properties of their constituent elements or molecules. This is because the atoms or molecules in a compound are chemically bonded, resulting in a new substance with its own distinct properties.
